ERNST FEEDRIK NYIDAHL, 0F AUGUSTENDAL, SWEDEN.

MOTOR-PLOW.

Application filed October 29, 1913.

1" 0 all whom it may concern:

Be it known that I, ERNs'r FREDRIK NYDAHL, subject of the King of Sweden, and resident of Augustendal, Sweden, have invented new and useful Improvements in Motor-Flows, of which the following is aspecification, reference being had to the drawings accompanying and forming a part hereof.

My invention relates to motor plows or the like of the class in which the plowshare or.

shares are secured to one or more plowbeams or traction rods adapted to swing in vertical direction. I

The present arrangement is appllcable to plows driven by an engine placed on the plow and driving the traction wheels of the plow as well as to plows moved by means of ropes or the like across the field to be plowed. D

The principal object of the inventlon is to provide areliable guidance for the plowshares in the lateral directions so that the shares simultaneously with their vertical movements shall assume a determinate position in the lateral direction, at the same time preventing the plow-beams from being bent if the shares strike stones or other impediments.

For the said purpose the invention consists in this that the plow-beams or traction rods at or, near the ends, that are connected to the shares, are guided in the lateral dis-w 1 movable in vertical direction relative to said guiding members which are movable per 86 in same direction and, consequently, need not extend too far in the direction of height. Besides, the guiding members, if necessary may be adjustable in lateral direction so that the distance between the plowshares and the plow-furrows may be varied.

The invention is illustrated in the accompanying drawings in which Figure 1 shows a lateral view of a part of a motor plow provided with the present invention and Fig. 2 same part viewed from above.

Referring to the drawings, 1 is the main frame of the motor plow and 2, are three horizontal shafts journaled in said main frame and carrying the guiding members 3 each of which is movably connected to a shaft 2. Each of the guiding members consists of two bends or the like'the shanks of which for the greater part of their length,

guiding members is limited by'rollers 6 journaled in said members, and, if necessary, also the upward movement of the plow-beams in the guiding members may be limited by means of such rollers.

The guiding members 3 are adjustable in lateral direction on the shafts 2 and maintained in the desired positions by adjusting rings 7 connected to the shaft by set-screws or the like. In case a guiding member is to be dislocated it is only necessary to remove the set-screws from the adjusting rings and then to move the guiding member along the shaft. In this manner the distance between the plow-furrows may, obviously, be varied, as desired.

In order that the guiding members shall adjust themselves according to the unevenness of the ground, the said members are supported on wheels 8 limiting the downward movement of the members as well as the depth of the plow-furrows. If desired, the. guiding members may be connected to a lifting device (not shown) by means of which they may be turned so that the shares are raised from the ground. The fore-ends of the plow-beams are in the usual manner connected to rods attached to the main frame of the plow.

The form of the arrangement shown on the drawing may be varied in different manners without deviating from the principles of the invention. Thus, for instance, the guiding members may, instead of being movable about the shafts 2, move in vertical direction between guides located on the main frame of the plow.

I claim:

1. In a motor plow, the combination of a frame, guiding members mounted independently of each other in said frame so as to be movable in a vertical direction but immovable in a lateral direction, a plow beam movable in a vertical direction in each of said guiding members and guided by the same against lateral movement, and plowshares attached to the plow beams, substantially as and for the purpose set forth.

2. In a motor plow, the combination of a frame, guiding members mounted independently of each other in said frame so as to be movable in a vertical direction but immovable in a lateral direction, means for limiting the downward movement of the guiding members, a plow beam movable in a vertical direction in each of said guiding members and guided by the same against lateral movement, and plow-shares attached to the plow beams, substantially as and for the purpose set forth.

3. In a motor plow, the combination of a frame, guiding members mounted independently of each other in said frame so as to be movable in a vertical direction but immovable in a lateral direction, a plow beam movable in a vertical direction in each of said guiding members and guided by the same against lateral movement, means for limiting the downward movement of the plow beam in the guiding member, and plow-shares attached to the plow beams, substantially as and for the purpose set forth.

l. In a motor plow, the combination of a frame, guiding members mounted independently of each other in said frame so as to be movable in vertical direction but immovable in a lateral direction, means for adjusting said guiding members in a lateral direction relatively to the frame, a plow beam movable in a vertical direction in each of said guiding members and guided by the same against lateral movement, and plow shares-attached to the plow beams, substantially' as and for the purpose set forth.

5. In a motor plow, the combination of a frame, guiding members mounted independently of each other in said frame so as to be movable in a vertical direction but immovable in a lateral direction, said guiding members being formed with bends and being arranged in pairs with theirshanks substantially parallel, a plow beam movable in a vertical direction in each of said guiding members and guided by the same against lateral movement, and plow-shares attached to the plow beams, substantially as and for the purpose set forth.

6. In a motor plow, the combination of a frame, a plurality of horizontally disposed shafts *journaled to the said frame, guiding members pivotally mounted at one end to said shafts independently of each other, a plow beam'mo-v'able in a vertical direction in each .of said guiding members and guided by the same against lateral movement, and plow-shares attached to the plow beams, substantially as and for the purpose set forth. I

7. In amotor plow, thecombination of a frame, a plurality of horizontally disposed shafts journaled to the said frame, guiding members pivotally mounted at one end to said shafts independently of each other, col.- lars mounted on said shafts and adapted to engage with said guiding members, means for securing the collars in position, a plow beam movable in a vertical direction in each of said guiding members and guided by the same against lateral movement, and plowshares attached to the plow beams, substantially as and for the purpose set forth.
